IMPROVEMENT IN THUMB-RESTS FOR SHEEP-SHEARS.

Specification forming part of Letters Patent No. 202,469, dated April16, 1878; application filed September 14, 1877.

To all whom it may concern:

Be it known that I, JOHN RICHARDSON, J R., of Pomona, in the county ofLos Angeles and State of California, have invented a new and ImprovedThumb-Rest for Sheep-Shears, of which the following is a specificationThis invention relates to means for protecting the thumb while usingsheepshears; and the nature of my invention consists in a detachableconcave thumb-rest, which is formed on a shank adapted to fit thegrasping portion of the shears and to be secured thereto, as will behereinafter more fully described and claimed.

In the annexed drawing, Figure l is a side view of the thumb-restapplied to a pair of sheep-shears. Fig. 2 is a top View of the de vice,and Fig. 3 is a bottom view of the same.

Similar letters of reference indicate corresponding parts.

The letter A designates an oblong plate, which has one side concave toaflord a comfortable rest to the ball of the thumb while grasping a pairof shears. Opposite to the concave side of the thumb-rest its surface isbeveled longitudinally, and at one corner of it is a triangular lug, a.Opposite to the lug a the thumb-rest is formed on an arched portion, A,of a shank, B.

The shank B, beyond the arch A, is nearly straight, and its flat sidelies on the inner side of the grasping portion of the shears, and thebeveled side of the plate A rests against the outer edge of theshear-blade. In this position of the thumb-rest and its shank the latteris secured to the shears by a cord.

When the shears, having my improvement applied to them, are grasped inthe hand, the plate A will afford a good bearing or rest for the thumb,and will not injure the same.

Having thus described my invention I claim as new and desire to secureby Letters Patent A detachable thumb-rest for sheep-shears, consistingof the concave rest A, the arch A and the shank B, all shapedsubstantially as shown and described.
